Development and Application of Voxelized Dosimetric Models for Biota : Characterization of the Uncertainty in the International Commission on Radiological Protection's Wildlife Dosimetry System

Creator:: Caffrey, Emily Amanda
Abstract:: A system for radiological dosimetry for nonhuman biota developed by International Commission on Radiological Protection (ICRP) relies on calculations that utilize the Monte Carlo simulations of simple, ellipsoidal geometries with internal radioactivity distributed homogeneously throughout. In this manner it is quick and easy to estimate whole-body dose rates to biota....

Improvements in the dosimetric models of selected benthic organisms

Creator:: Caffrey, Emily Amanda
Abstract:: The International Commission on Radiological Protection (ICRP) has modeled twelve reference animal and plant (RAP) species using simple geometric shapes in Monte–Carlo (MCNP) based simulations. The focus has now shifted to creating voxel phantoms of each RAP to advance the understanding of radiation interactions in nonhuman biota. The work contained...

Examination of uranium uptake by root vegetables and consequences for human consumption

Creator:: AlZahrani, Abdullah Bakheet
Abstract:: Uranium is the most common radionuclide that found in the nature. It is a radionuclide with a very low specific activity. There is limited data on plan uptake of uranium. This research was to determine the plant uptake of uranium, calculate the concentration ratio, and estimate the dose from eating...

Environmental pathway analysis of a radioactive zirconium sand uploading facility

Creator:: Miller, Robert E.
Abstract:: The Teledyne Wah Chang facility is a manufacturer of the rare metal zirconium. The facility has been in constant production since 1956. In 1973 an attempt to utilize different sand ore sources from Nigeria and India in a new carbiding process, prior to chlorination, failed. The resulting byproducts of the...

A study of residual Cesium 137 contamination in southwestern Utah soil following the nuclear weapons tests at the Nevada Test Site in the 1950's and 1960's

Creator:: Bentley, R. Blair
Abstract:: The Nevada Test Site (NTS) was the location for at least 100 above ground Nuclear Weapons tests during the 1950's and early 1960's. Radioactive fallout from these tests spread to many areas north and west of the NTS. According to estimates from the NCI and DOE, Washington County, Utah was...

Radioanalysis of oceanic organisms in the Pacific Ocean off Oregon

Creator:: Osterberg, Charles L.
Abstract:: Our major effort since initiation of this contract has been directed toward (1) procuring the gamma-ray spectrometric equipment and integrating the components into an operational system, and (2) analyzing the samples obtained from the midwater trawl program of the Department of Oceanography and evaluating and interpreting the resulting data Analyses...

Radioanalysis of oceanic organisms in the Pacific Ocean off Oregon

Creator:: Osterberg, Charles L.
Abstract:: This report covers the first full year of operation of our gammaray spectrometry facility. A part of the contract period was devoted to calibration of the instrument, and therefore, a brief report on this procedure is included.

Use of GIS software to map contaminant distributions and determine integrated dose for purposes of assessing impact to biota

Creator:: Myers, Margaret C.
Abstract:: The objective of this research was to estimate the radiological impact on various non-human biotas by the Fukushima Daiichi Nuclear power plant radiation release resulting from Japan's tsunami in March 2011 consistent with the recent recommendations of the International Commission on Radiological Protection. Soil concentration data given by Japan's Ministry...

An analysis of the viability of ranked set sample methodologies based on the evaluation of Dyess AFB B-47 crash site radiological contamination survey data and theoretical modifications

Creator:: Miller, Vivien J.
Abstract:: Since Ranked Set Sampling (RSS) was proposed in 1952 by G.A. McIntyre, it has been the subject of many statistical investigations and a large number of field studies. Throughout these studies RSS has been proven to provide a better estimate of population the mean and variance than Simple Random Sampling...
